摘　　要：报道了我国几种淡水鱼鱼鳞基本化学组成 ,并考察了鱼鳞对高脂饲料大鼠甘油三酸酯 (TG)和总胆固醇 (TC)的影响。结果表明 ,鱼鳞粗蛋白质含量为 4 0 %～ 80 % ,糖、脂肪含量极低 ;氨基酸组成中 ,甘氨酸含量极高 ,并含有较多的天冬氨酸、谷氨酸、丙氨酸、精氨酸、脯氨酸、羟脯氨酸。矿物元素以钙、磷含量较高。鱼鳞可有效防止大鼠实验性高胆固醇血症 。Ten kg of fresh water fish scales were collected and smashed after cleaned and dried. The experimental rats, body weight 220～250 g, were fed high lipid feed for 1 week and then fed basic diet mixed with different centent of fish scale (5% or 10%) for 30 d. The serum lipid, TC and TG in the rats were analysed. The results show that in the fish scale, there is 40%～80% protein, but the contents of saccharide and fat are very low; the content of glycine is considerably high and there are abundant aspartic acid, glutamic acid, alanine, arginine, proline, hydroxyproline; the contents of Ca and P are higher among the mineral elements in the scale. The animal test shows that fish scale has the function of preventing formation of high cholesterol in experimental rats and can reduce total cholesterol and total glyceride levels in experimental hypercholesterolemic rats.
